Earlier this week, the 31-year-old reality star revealed that she had contracted a staph infection while staying with estranged husband Lamar Odom in the hospital. And now, the star is giving an update on her health that shows the true cause behind the scary bacteria-borne illness.

"Staph infection is no joke," the star wrote on Twitter on Saturday, Nov. 21. "Mine was exacerbated by stress which is not a great combo. I'm under great medical care&receiving tons of love!"

The Keeping Up With the Kardashians star has faced her fair share of stress in recent months. In October, Odom was found unresponsive in a Nevada brothel and has been under a steady recovery since.

The scary health problems have also caused the star to cancel signings of her newly-released book Strong Looks Better Naked, but the brunette beauty is on her way to recovery, and is thanking her fans and supporters for their well wishes.
